Abstract [en]
The paper proposes a solution for the problem of target angular observation and specular reflection of elongated structure in SAR change detection. To illuminate a certain target at different angles and/or to minimize specular reflection, a natural solution is to pass the ground scene several times using different flight tracks. This helps to increase the detection probability and reduce the false alarm rate simultaneously. To evaluate the proposal, we use a simple statistical hypothesis test derived from bivariate Rayleigh distribution and the CARABAS data. A comparison based on the detection probability and false alarm rate with other available SAR change detection method reveals the benefit of the proposal. © 2019 IEEE.
